Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, specifically a high-viscosity asphalt-based coating kneading machine. Background Technology

[0002] Asphalt-based coatings are waterproofing or bonding materials made from petroleum asphalt or coal tar pitch as a base, with the addition of polymers, solvents, or emulsifiers. They can be classified into solvent-based and water-emulsion types based on their form, and are widely used in building waterproofing, bridge engineering, and other fields. Asphalt-based coatings mainly include solvent-based asphalt coatings, water-emulsion asphalt coatings, and polymer-modified asphalt-based coatings. Polymer-modified asphalt-based coatings, in particular, involve adding composite polymers (such as SBS and rubber-like materials) to asphalt to improve the coating's toughness and impermeability, making them suitable for high-requirement waterproofing applications. However, polymer-modified asphalt-based coatings are characterized by high viscosity and poor flowability, requiring kneading during the batching process. In existing technologies, conventional kneaders are ineffective at mixing such lumpy, high-viscosity coatings, resulting in lengthy processing times and poor uniformity of the finished product. Summary of the Invention

[0003] This utility model aims to address the technical deficiencies of existing technologies by providing a high-viscosity asphalt-based coating kneader, thereby solving the technical problem that the mixing effect of high-viscosity asphalt-based coatings in conventional kneaders needs to be improved.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution:

[0005] A high-viscosity asphalt-based coating kneader includes a machine chamber, a first end cap, a first geared motor, a first kneading roller, a second geared motor, a second kneading roller, a second end cap, a cavity, a branch pipe, a sealing strip, and a replenishment pipe. The machine chamber contains a cavity with a port at its upper end. A first end cap and a second end cap are hinged to both sides of the port. The first and second kneading rollers are rotatably connected inside the cavity. The first and second geared motors are fixedly connected to the outer wall of the machine chamber. The first geared motor is drive-connected to the first kneading roller, and the second geared motor is drive-connected to the second kneading roller. A sealing strip is provided at the joint between the first end cap and the second end cap. Several branch pipes extending into the cavity are provided on the first end cap and the second end cap, and each branch pipe is connected to the replenishing pipe. The first kneading roller and the second kneading roller each include a main shaft, a continuous threaded strip, a threaded segment strip, a radial rod, and a blade. Several radial rods are fixedly connected to the outside of the main shaft. A continuous threaded strip is connected between several radial rods. A threaded segment strip is connected between two radial rods that are perpendicular to each other. The diameter of the threaded segment strip is smaller than the diameter of the continuous threaded strip. A blade is fixedly connected to the end of the radial rod.

[0006] Preferably, a side cover plate connected to the cavity is provided at the side end of the machine compartment, and a discharge door connected to the cavity is provided at the bottom end of the machine compartment.

[0007] Preferably, an electric heater is built into the side wall of the cabin.

[0008] Preferably, the first end cover and the second end cover are fixedly connected to the machine compartment rather than hinged, and feed pipes are provided on the first end cover and the second end cover.

[0009] Preferably, several retaining rings are fixedly connected to the outer wall of the spindle.

[0010] Preferably, the connection between the continuous threaded strip and the radial rod, as well as the connection between the threaded segment strip and the radial rod, are achieved by clamping bolts.

[0011] Preferably, the width of the continuous thread strip is smaller than the width of the thread segment strip, and a central ridge is provided in the middle of the thread segment strip.

[0012] In the above technical solution, the machine compartment is the basic structure of this utility model, which is used to contain the material. The internal cavity is a space for kneading and mixing the material. The first end cover and the second end cover can be hinged and opened for feeding, or they can be designed as fixed covers, in which case a feeding pipe needs to be added for feeding. The first geared motor and the second geared motor are used to drive the first kneading roller and the second kneading roller to rotate, and to stir and knead the asphalt-based coating inside the cavity. The liquid replenishment pipe can be used to connect to the solvent end, and can replenish the mixture during the stirring and kneading process. The branch pipe at its end extends into the cavity to play a certain role in liquid distribution. The sealing strip can be a rubber strip or a rubber edging sleeve on the outer periphery of the end cover, which is used to play a certain role in sealing the joint between the two end covers. This invention features a novel kneading roller design. Its main shaft can be connected to a geared motor via a coupling. A radial rod with blades at the end is located on the outside of the main shaft, which acts as a lever during shaft rotation. Simultaneously, a large-diameter continuous threaded strip is added based on the radial rod, providing axial pushing force on the material during rotation. Inside the continuous threaded strip are several threaded segments, which shear and push the material during rotation, promoting material movement near the shaft. Combined with the counter-rotating motion of the two kneading rollers, this achieves mixing and kneading of the material. In a preferred embodiment, this invention can be supplemented with a side cover plate for maintenance; a retaining ring can be added to the outside of the main shaft to help alleviate the phenomenon of slurry snagging on the shaft.

[0013] This invention provides a high-viscosity asphalt-based coating kneader. The technical solution employs dual kneading rollers rotating in opposite directions within a confined space to achieve mixing and kneading of high-viscosity slurry. Based on this, the kneading roller structure is improved, and the feeding mode is optimized. This invention helps to improve the mixing speed and the uniformity of the final product, and its functionality is also enhanced to a certain extent. Attached Figure Description
